In the Perl programming language, grep is the name of the built-in function that finds elements in a list that satisfy a certain property. This higher-order function is typically named filter in functional programming languages. The pcregrep command is an implementation of grep that uses Perl regular expression syntax. Similar functionality can be invoked in the GNU version of grep with the -P flag. Ports of grep (within Cygwin and GnuWin32, for example) also run under Microsoft Windows. Some versions of Windows feature the similar qgrep or Findstr command.

During meiosis, two successive nuclear divisions happens namely Meiosis I or reduction and Meiosis II or division. In meiosis I, it separate chromosomes after allowing crossing over. In meiosis II, it the then separates each chromosomes by splitting them. This division produces 4 haploid cells.
Meiosis is a reduction division meaning it needs to reduce the number of chromosomes to half. The first division (MEIOSIS I) only includes the separation of homologous chromosomes or tetrads, the second division (MEIOSIS II) is the same as mitosis, meaning it separates sister chromatids from each other, resulting to half the number of chromosomes from the parent.
